Stainless Steel for Charging Equipment
Stainless steel is often selected for EV charging and electrical equipment when corrosion resistance, structural durability, appearance, or cleaning requirements are important.
● 304 stainless steel for general industrial enclosure applications
● 316 stainless steel when the project requires stronger corrosion resistance
● Brushed surfaces for visible stainless steel panels
● Powder-coated stainless steel when specified for appearance or project requirements
Fabrication Capabilities
